Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
qua cham » qua hai, qua cac, va cham
hanh lai » hanh lam, hanh tai, thanh lap
dang xay » dang van, van xay
cua tre » cua te, cua triet, dua tren
va hanh » van hanh, va thanh, va danh
so sach » so sanh, bo sach, co sach
sach ty » sach y, sach tu, sach thu
cuu tre » cau tren, cau treo
xuc va » duc va, tuc va, luc va

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty ((nang x) OR (dang xay)) hoi. hieu qua cham xuc va hanh lai ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty ((nang x) or (dang xay)) hoi. hieu qua cham xuc va hanh lai ((cua tre) OR (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: so sach ty ((nang x) or (dang xay)) hoi. hieu qua cham xuc va hanh lai ((cua tre) OR (cuu tre))*.
